The STWLC04 is an integrated wireless power receiver suitable for wearable applications. The STWLC04 is focused on 1-watt power transfer based on Qi protocol with digital control and precise analog control loops ensuring stable operation. Together with the STWBC-WA transmitter, the STWLC04 enables a complete wireless power transmission. I2C interface allows many parameters to be customized in the device and this configuration can be stored in the embedded NVM.
The STWLC04 can deliver the output power in two modes: as a power supply with configured output voltage or as a simple CC/CV battery charger with configurable charging current, charging voltage and termination current. The STWLC04 can detect the external (wired) power supply connection and drive an external power switch.
